On-loan Manchester United winger Wilfried Zaha has not decided whether he would like to return to Old Trafford or re-join Crystal Palace on a permanent basis.

Zaha returned to Selhurst Park a season-long loan last summer but struggled to find form under the management of Neil Warnock.

Under Alan Pardew, though, the 22-year-old has again began to show the kind of form that convinced Sir Alex Ferguson to sign him from Palace for £15m in January 2013, in what turned out to be the Scot's last signing as manager at Old Trafford.

While he admits it is too soon to make any announcement over his long-term future, Zaha admits a permanent return to south-east London would interest him.

"I can't answer that right now," Zaha told the South London Press when quizzed on his future. "Coming back to Palace would be great but that is in the future, so I'll decide then."

Zaha's career at Old Trafford has yet to take off since his move. During United's shambolic campaign under David Moyes last term, the winger made just two appearances before joining Cardiff City on loan until the end of the season, where he was unable to help the club avoid relegation.
